    • A support plate unit comprises a pair of extension plates (1) interlinked by a connecting plate (2) by means of pivot pins (3). The extent of rotation of each extension plate (1) with respect to the connecting plate (2) is limited by means of respective pins (4) sliding within slots (5) in the connecting plates (1). Edges of the extension plates abut in the fully extended condition such that the extension plates extend longitudinally away from one another at an angle less than 180 DEG with respect to the inside edge (6) of the unit. This prevents over extension of the joint with which the support unit is associated. However, the joint can be bent as fully as necessary in the other direction. The pin and slot configurations (4 and 5) ensure that, during an intermediate flexing of the unit, neither of the extension plates can rotate so far with respect to the connecting plate (2) as to cause parts of the plates to project in a dangerous manner.
    • 支撑板单元包括通过枢轴销(3)由连接板(2)互连的一对延伸板(1)。 每个延伸板(1)相对于连接板(2)的旋转程度通过在连接板(1)中的槽(5)内滑动的相应销(4)来限制。 延伸板的边缘在完全延伸的状态下抵接,使得延伸板相对于单元的内边缘(6)以相对于180°的角度彼此纵向延伸。 这防止了与支撑单元相关联的关节的过度延伸。 然而,可以根据需要在另一方向上完全弯曲接头。 销和槽配置(4和5)确保在单元的中间弯曲期间,两个延伸板都不能相对于连接板(2)旋转到远,使得板的一部分投射在 危险的方式。
